Used toothbrush bristles,SEM
Used toothbrush bristles. Coloured scanning electron micrograph (SEM) of dental plaque on the bristles of a used toothbrush. Plaque consists of a film of bacteria embedded in a glycoprotein matrix. The matrix is formed from bacterial secretions and saliva. Plaque is the main cause of tooth decay. The bacteria feed on sugars in food,producing acid as a waste product. This acid corrodes the teeth's enamel coating,resulting in dental caries. A build-up of dental plaque can also lead to inflamed and infected gums. Severe gum disease can lead to teeth falling out.
